To calculate the impulse, we need to multiply the force by the time it was applied for. From the figure, we can see that the force is 4 N and it was applied for 1 second. Therefore, the impulse is 4 N x 1 s = 4 Ns, which can also be written as 4 mN F1S1. The closest choice to this answer is C, which is 4.0 mN F1S1 x 10 s = 40 mN F1S1 or 40 Ns. None of the other choices match this calculation.
